DEVICE: SAPIEN 3 Ultra System (00690103207828)

An implantable xenograft (e.g., bovine, porcine) intended to be used to repair/replace a stenosed and/or regurgitant aortic heart valve, or previously-implanted aortic heart valve prosthesis, and which is designed to be implanted with a catheter via transarterial access (e.g., femoral, subclavian, aortic) or transapical access while the heart is beating. It is comprised of the xenograft, processed to render the tissue non-viable, attached to an expandable metal framework, which is implanted with an included catheter, and when in situ, may be expanded with a balloon or self-expand. Typically devices associated with implantation (e.g., catheter, introducer) are included.

An implantable xenograft (e.g., bovine) intended to be used to repair/replace a stenosed or regurgitant mitral heart valve, or previously-implanted mitral heart valve prosthesis, and which is implanted with a catheter via percutaneous access (e.g., transfemoral, transapical) while the heart is beating. It is comprised of the xenograft, processed to render the tissue non-viable, attached to a metal framework (which may be covered with a synthetic polymer material) that is expandable in situ; it may also include a synthetic polymer subannular valve anchoring component. Devices to assist implantation (e.g., catheter, introducer) are typically included.
